'''Crustaceans''' are a large, diverse group of [[arthropods]], including familiar animals such as [[crabs]], [[lobsters]], [[crayfish]], [[shrimp]], [[krill]], and [[barnacles]]. The crustacean group can be treated as a [[subphylum]] under the [[phylum]] Arthropoda, and is usually divided into classes.

== Characteristics ==

Crustaceans are generally aquatic and differ from other arthropods in their body structure and function. They have two pairs of [[antennae]], a pair of mandibles, and two pairs of maxillae on their heads. They also have a hard [[exoskeleton]] that protects their bodies.

== Classification ==

Crustaceans are typically classified into the following classes:

* [[Class Malacostraca]]: This includes crabs, lobsters, crayfish, shrimp, krill, woodlice, and others.
* [[Class Branchiopoda]]: This includes brine shrimp and Daphnia.
* [[Class Cephalocarida]]: This includes horseshoe shrimp.
* [[Class Maxillopoda]]: This includes barnacles, copepods, and a number of related animals.
* [[Class Ostracoda]]: This includes seed shrimp.

== Ecology and Life Cycle ==

Crustaceans play key roles in marine and freshwater ecosystems, where they serve as the primary consumers of algae and detritus, and as prey for numerous larger animals. The life cycle of crustaceans varies greatly, but most species hatch from eggs as a larva that undergoes several stages of development before reaching adulthood.

== Economic Importance ==

Many crustaceans are vital to human economies and are among the most widely consumed types of seafood worldwide. They are also used in research and are important indicators of ecosystem health.
